No true but the as far as I understand it WDM drivers are completely separate from the ASIO version, hence the "symptom of a poor driver" comment. Just your WDM driver is poor and the ASIO fine.
WDM isn't obsolete by any means. To start with if you want to run more than one device your only option is WDM, ASIO only allows for one driver to be used at a time.
WDM isn't good for me but there's plenty of people here using it and getting better results than they do from ASIO. It's just down to how good the drivers are.
